2011-01-27Revert r124217 because it didn't catch the actual error case it was trying toJeffrey Yasskin
catch: lock_guard(my_mutex); declares a variable instead of creating a temporary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124398 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-25Add an attribute to forbid temporary instances of a type. This allows classJeffrey Yasskin
authors to write class __attribute__((forbid_temporaries)) Name { ... }; when they want to force users to name all variables of the type. This protects people from doing things like creating a scoped_lock that only lives for a single statement instead of an entire scope. The warning produced by this attribute can be disabled by -Wno-forbid-temporaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124217 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-21Sema: support for processing non-inheritable declaration attributes earlyPeter Collingbourne
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123960 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-05Refactor the application of type attributes so that attributes fromJohn McCall
the declaration-specifiers and on the declarator itself are moved to the appropriate declarator chunk. This permits a greatly simplified model for how to apply these attributes, as well as allowing a much more efficient query for the GC attribute. Now all qualifier queries follow the same basic strategy of "local qualifiers, local qualifiers on the canonical type, then look through arrays". This can be easily optimized by changing the canonical qualified-array-type representation. Do not process type attributes as decl attributes on declarations with declarators. When computing the type of a block, synthesize a prototype function declarator chunk if the decl-spec type was not a function. This simplifies the logic for building block signatures. Change the logic which inserts an objc_read_weak on a block literal to only fire if the block has a __weak __block variable, rather than if the return type of the block is __weak qualified, which is not actually a sensible thing to ask. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122871 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Re-work the handling of implicit 'this' arguments and silly GCC-style attributeChandler Carruth
argument indexes. This handles the offsets in a consistent manner for all of the attributes which I saw working with these concepts. I've also added tests for the attribute that motivated this: nonnull. I consolidated the tests for format attributes into one file, and fleshed them out a bit to trigger more of the warning cases. Also improved the quality of some of the diagnostics that occur with invalid argument indices. The only really questionable change here is supporting the implicit this argument for the ownership attribute. I'm not sure it's really a sensible concept there, but implemented the logic for consistency. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119339 91177308-0d34-0410-b5e6-96231b3b80d8
